Questions + Answers key
Take MCQ Chemistry Test1.
Define orbital ? what are the n and 1 values for 3px and 4dx2-y2 electron ?
2.
Consider the following electronic arrangements for the d5 configuration.
(a)
| \(\upharpoonleft \downharpoonright \) | \(\upharpoonleft \downharpoonright \) | \(\upharpoonleft \) |
(b)
| \(\upharpoonleft \) | \(\upharpoonleft \) | \(\upharpoonleft \) | \(\upharpoonleft \downharpoonright \) |
(c)
| \(\upharpoonleft \) | \(\upharpoonleft \) | \(\upharpoonleft \) | \(\upharpoonleft \) | \(\upharpoonleft \) |
which of these represents the ground state
3.
Which quantum number reveal information about the shape, energy, orientation and size of orbitals?
4.
How many orbitals are possible for n = 4?
5.
For each of the following, give the sub level designation, the allowable m values and the number of orbitals
(i) n = 4, l = 2
(ii) n = 5, l = 3
(iii) n = 7, l = 0
1.
The solution to Schrodinger equation gives the permitted total energy values called eigen values and the corresponding wave function represent atomic orbitals.
| Orbital | n | l |
| 3px | 3 | 1 |
| 4dx2-y2 | 4 | 2 |
2.
(i) ground state :
| \(\upharpoonleft \) | \(\upharpoonleft \) | \(\upharpoonleft \) | \(\upharpoonleft \) | \(\upharpoonleft \) |
This type of electronic configuration have ten possible arrangement (i.e. Half filled configuration is More).
3.
a) Principal quantum number defines energy and size of an orbital.
b) Azimuthal quantum number defines shape of an orbital
c) Magnetic quantum number defines spatial orientation (direction) of an orbital.
4.
| n | l | m | orbitals | Total no of orbitals |
